试验结果表明,分级时效工艺在提高合金机械性能的同时,还能使合金抗应力腐蚀性能得到明显改善。
Experimental results show that stepped aging process not only enhances mechanical properties but also improves resistance against stress corrosion of the alloy.
分级时效处理,低温下先让合金内部的宏观应力松弛,再在较高温度下时效,可有效地避免棒材纵向开裂。
However, stepped aging, which relaxes internal macro-stress under lower temperature then ages under higher temperature, can avoid longitudinal cracks effectively.
结果表明,NBC合金经过分级时效处理后, 耐磨性、 耐腐蚀性和电导率有所提高,而显微硬度无明显变化;
The results show that multi-stage aging treatment can increase wear resistance, corrosion resistance and electrical properties of NBC alloy, but microhardness has not changing apparently.
